The purpose of this narrative review is to describe the different nerve-sparing techniques applied during radical prostatectomy and document their functional impact on postoperative outcomes. We performed a PubMed search of the literature using the keywords “nerve-sparing”, “techniques”, “prostatectomy” and “outcomes”. Other potentially eligible studies were retrieved using the reference list of the included studies. Nerve-sparing techniques can be distinguished based on the fascial planes of dissection (intrafascial, interfascial or extrafascial), the direction of dissection (retrograde or antegrade), the timing of the neurovascular bundle dissection off the prostate (early vs. late release), the use of cautery, the application of traction and the number of the neurovascular bundles which are preserved. Despite this rough categorisation, many techniques have been developed which cannot be integrated in one of the categories described above. Moreover, emerging technologies have entered the nerve-sparing field, making its future even more promising. Bilateral nerve-sparing of maximal extent, athermal dissection of the neurovascular bundles with avoidance of traction and utilization of the correct planes remain the basic principles for achieving optimum functional outcomes. Given that potency and continence outcomes after radical prostatectomy are multifactorial endpoints in addition to the difficulty in their postoperative assessment and the well-documented discrepancy existing in their definition, safe conclusions about the superiority of one technique over the other cannot be easily drawn. Further studies, comparing the different nerve-sparing techniques, are necessary.

Objectives: The clinical value and efficiency of hands-on training courses in percutaneous nephrolithotomy (PCNL) remains undocumented. During the last 9 years, a two-day international intensive hands-on training course in fluoroscopic guided prone PCNL is taking place in our department on a monthly basis. Course includes wet lab training in the porcine model and live surgery training. In this work we report the outcomes of a survey send to course participants questioning the impact of the course to their clinical practice.Materials and methods: A survey consisting of 26 questions was distributed online to a total of 91 trainees that had completed the course. Comparison of pre and post course surgical practices was performed using the "N-1" Chi-squared test.Results: A total of 64 trainees responded to our online survey with 55.6% and 41.3% reporting a modest or major impact to their practice accordingly. Notable changes in puncture and dilation technique were evidenced while a uniform reduction in puncture and operative times was documented. 79.4% responded that the course increased the safety of their procedure, 73% that it reduced operating times, 39.7% that increased their stone free rates, 23.8% that reduced their complications and 23.8% that induced to change their instrumentation with respect of that they were using in the past. Subgroup analysis including only well experienced surgeons revealed a similar impact to their practice.Conclusions: In the proper setting, an intensive hands-on PCNL course can have a significant impact on attending physicians. Participation to such events even for experienced surgeons should be encouraged.
